OIL-BURNER.

To all whom it may concern Be it known that I, GEORGE E. WIN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to an oil burner.

One of the objects of the present invention is to provide a simple, substantial, cheaply manufactured burner of the rotary type by which the oil is projected and atomized by centrifugal force.

Another object is to provide means for delivering oil to the burner and evenly dis tributing it therein; and to provide means operable in unison with the burner for forcing air through andexterior of the burner. Further objects will hereinafter appear. The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a central section of the burner. Fig. 2 is a front view. Fig. 3 is a rear view. Fig. 4 is a partial section of a furnace showing the installation of the burner.

A indicates a conical-shaped rotor or burner head, 2 a hub concentrically positioned with relation to the head, and '3 a plurality offan-shaped spokes, which support the conical-shaped head with relation to the hub 2 and a shaft 4. The inner contracted end of the head is opened as indicated at 5, thus permitting the insertion of force against the inner face of the coneshaped rotor and will gradually work in an outward direction through the spaces formed between the several fan-shaped spokes 3, before it is finally permitted to l'eavethe annular discharge flange or lip indicated at 7. This discharge flange is considerably larger in diameter than the conical portion of the head and is provided for the purpose of increasing the area over which the oil flows before it is finally liberated. The oil film is thus gradually thinned out as the surface area increases and is at the same time heated to a more or less extent as the face of the rotor is subjected to the radiated l H Specification of Letters Patent.

subjected to the action-of centrifugal force, will be projected'in a highly atomized condition and will burn within a very few inches of the burner.

Suitably secured on the exterior surface of the cone'A, and in back of the discharge is a plurality of angularly disposed vanes 8. These vanes are provided for the purpose of inducing an air current which is discharged from the rotor directly behind the burning sheet' of oil. The air will thus have to pass through the flame area of theburner and will thoroughly mix with the particles of hydrocarbon projected and form a perfect combustible mixture. I

flange 7 or formed integrally with therotor,

In actual practice, it has been found tha back fire to the burner proper, as the air passing through throws the flame in an outward direction.

Referring to Fig. 4,the installation of the burner is shown. The burner is preferably partly inclosed by a tube-like casing 9. The air current is in this manner drawn through the casing and burner in the direction of arrows a and will in this manner strike the rear face of the burner. preventing it from becoming overheated. The rotor and shaft may be mounted and driven in any suitable manner, but are preferably directly connected to an electric motor or like driving means, indicated at'll. The oil delivered by the pipe 5 may be raised to the burner The driving mechanism, together with theoil delivering means. does not form any part of the present. invention.

A burner constructed as here shown is preferably placed in a horizontal casing 9 in front of the boilei It is in this manner kept out of the intense heat as the air passin buner andforces the heat toward the back of the boiler or furnace;. the burner being near the fire door is easily accessible. A burner of this construction cannot be flooded or overflow as all oil delivered will be dis through the casing and burner cools the charged directly into the furnace where it is immediately consumed. The grate bars can be entirely removed from a furnace Where a burner of this type is installed and the burner may be practically surrounded by brick-work which retains the high temperature in the fire box, improving combustion,.

and enabling the burner to operate with a small fire without going out. The burner is, furthermore, cheap, simple and substantial' in construction, and does not require skilled labor for successful installation and operation. The materials and finish of the several parts of the burner are such as the experience and judgment of the manufacturer may dictate. a

I wish it understood that various changes in form, proportions and minor details of porting shaft extending through and secured in the hub, means for rotating the shaft, and means for delivering'oil to the interior of the head.

hub member,a plurality of fan-blades interposed between the hub and head, a supporting shaft extending through and secured in the hub, means for rotating the shaft, a discharge flange formed on the outer large end of the head, and means for delivering oil through the contracted inner end of the head.
